Sourced conceptual inventory per tonne of blended FT liquid fuel from H2 and captured CO2: feeds, product and utility power from one open process simulation (König et al. 2015), burner flue gas and water from the element balance. Electrolysis and capture are outside. No flowsheet; not reviewed.
Fischer-Tropsch e-fuel from CO2 and hydrogen by reverse water-gas shift and cobalt FT synthesis
Sourced conceptual inventory per tonne of blended FT liquid fuel from H2 and captured CO2: feeds, product and utility power from one open process simulation (König et al. 2015), burner flue gas and water from the element balance. Electrolysis and capture are outside. No flowsheet; not reviewed.
Research outputNot engineering advice and not an approved design: do not use it for construction, operation or safety decisions. What this means
Overview
- Capacity
- per tonne of FT liquid fuel (the dataset's basis); the source plant: 100 MW (LHV) of H2, 5.5 t/h fuel
What goes in and out
In
- HydrogenFeedstockfeed:H2: 3.01 t/h per 5.5 t/h fuel at 2.5 MPa; electrolytic hydrogen, supplier not chosen (lca/mappings.yaml)
- Carbon dioxideFeedstockfeed:CO2: 22.9 t/h per 5.5 t/h fuel at 0.1 MPa; captured CO2, taken as from a fossil point source (ASSUMED), supplier not chosen
Out
- Fischer-Tropsch liquid fuelMain product
- WastewaterWastereaction water, closes the source's mass balance
Utilities: Electricity (plant utilities only; the electrolyser's power is in the hydrogen)
Life cycle assessment

In the LCI database: system model, datasets and KPIs against the benchmarks
In the LCI database
- Status
- Preliminary 2 unmapped exchanges. Some exchanges have no background mapping yet: they are exported unlinked and count no burden, so the inventory is incomplete.
- System model
- attributional, cut-off (methodology 1.1.0)
- Allocation
- mass (single-output, from default) · product:fischer-tropsch-fuel 100 %
- Allocation findings
- none
- Change report
- Not available: this build has no change report against an earlier release.

KPI benchmark positions
| KPI | Value | Reference range | Position |
|---|---|---|---|
| Share of the CO2 carbon fed that ends in the liquid fuel | – kg/kg | 0.455 to 0.455 kg/kg | not evaluated |
| Liquid fuel LHV per LHV of the hydrogen fed | – MJ/MJ | 0.582 to 0.582 MJ/MJ | not evaluated |
| CO2 fed per t of Fischer-Tropsch liquid fuel | – t/t | 6.81 to 6.81 t/t | not evaluated |
| Electricity used by the synthesis plant per t of FT liquid fuel (electrolysis excluded) | – kWh/t | 1,369 to 1,369 kWh/t | not evaluated |
Maturity and review
Design maturity Concept (claimed): An idea or first flowsheet; numbers are rough. No independent engineering review yet. Automated checks passing is not a review.
Calculation maturity, from the checked evidenceNot assessed
The process has no maturity report (cheme maturity, checks/maturity.json), so no calculation maturity is established.
No level shownThe design maturity (Concept) is the manifest's claim, not evidence. A level appears here once the process's repository holds a current report from
cheme maturity --write.Artifact completeness
Which deliverables exist. They never raise a calculation maturity level: a drawing from unchecked numbers is still unchecked.
Not reported without a maturity report.
Independent review
Not independently reviewed
No independent engineering review yet. Automated checks passing is not a review.
Set by people only. Reaching a calculation maturity level or passing automated checks is not an independent review or an approval.
